Calla vs English Lavender Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Calla
Zantedeschia aethiopica
Zantedeschia aethiopica, commonly known as Calla Lily, is a rhizomatous herbaceous perennial prized for its elegant, trumpet-shaped spathes (modified leaves) that surround a central spadix. While often called a lily, it is not a true lily. It grows from rhizomes, producing large, arrow-shaped, glossy green leaves. It is primarily an outdoor plant, thriving in moist conditions. People grow it for its striking flowers, often used in bouquets and floral arrangements. It can be grown indoors, but requires specific conditions to thrive and may not flower as readily as outdoors.
English Lavender
Lavandula angustifolia
English Lavender is a perennial shrub known for its fragrant flowers and aromatic foliage. It typically grows to a height of 1-3 feet. The plant features narrow, gray-green leaves and produces spikes of purple flowers in the summer. It is primarily an outdoor plant, thriving in sunny, well-drained locations. People grow it for its ornamental value, fragrance, and use in aromatherapy and culinary applications. While it can be attempted indoors, it requires very specific conditions to thrive.

❓ Frequently Asked Questions — Comparing These Plants
Calla
What are the light requirements for Calla?
Calla lilies thrive in bright, indirect light. Direct sunlight can scorch their leaves, so avoid placing them in south-facing windows without some form of shading. An east- or west-facing window is ideal, providing ample light without the intensity of direct sun. If you notice the leaves becoming pale or the plant failing to bloom, it may not be receiving enough light. In such cases, consider supplementing with artificial grow lights. During the darker winter months, supplemental lighting is particularly beneficial to maintain healthy growth and encourage future blooms. Ensure the light is diffused to prevent leaf burn. Regular rotation of the plant ensures all sides receive adequate light, preventing uneven growth.
How do I care for Calla?
Calla lilies require bright, indirect light for optimal growth and blooming. Water thoroughly when the top inch of soil feels dry, ensuring proper drainage to prevent root rot. During the growing season (spring and summer), fertilize every 2-4 weeks with a balanced liquid fertilizer diluted to half strength to encourage flowering. Reduce watering and fertilization during the dormant period in fall and winter. Maintain a humidity level of 50-60%. Repot annually in spring using well-draining potting mix. Remove spent flowers to encourage more blooms. Monitor for pests like aphids and spider mites, and treat promptly if detected. Provide support for taller varieties to prevent them from bending. Rotate the plant regularly to ensure even growth and prevent leaning towards the light source. Protect from frost and freezing temperatures.
How do I propagate Calla?
Calla lilies can be propagated by division, stem cuttings (though less common), and keiki (small plantlets that sometimes form on the plant).
English Lavender
What are the light requirements for English Lavender?
English Lavender requires at least six to eight hours of direct sunlight per day to thrive and produce abundant blooms. Insufficient light can result in leggy growth, reduced flowering, and weaker plants. When grown indoors, place Lavender near a south-facing window where it can receive the most intense sunlight. If natural light is limited, supplement with grow lights to ensure adequate illumination. Rotate the plant regularly to ensure even exposure to light on all sides. In hot climates, some afternoon shade may be beneficial to prevent scorching. Monitor the plant for signs of light stress, such as pale leaves or elongated stems, and adjust its placement accordingly.
How do I care for English Lavender?
English Lavender thrives in full sun and well-draining soil. Water deeply but infrequently, allowing the soil to dry out completely between waterings. Overwatering is a common cause of root rot. Fertilize sparingly, using a balanced fertilizer in the spring. Prune annually after flowering to maintain shape and encourage bushier growth. Provide good air circulation to prevent fungal diseases. Protect from frost in colder climates. Choose a pot with drainage holes and use a well-draining potting mix specifically formulated for Mediterranean plants. Regularly remove spent flowers to encourage further blooming. Monitor for pests such as aphids or spider mites and treat accordingly. Maintain moderate humidity levels. Provide 6-8 hours of direct sunlight daily for optimal growth and flowering.
How do I propagate English Lavender?
Lavender can be propagated through stem cuttings or division. For stem cuttings, take 4-6 inch cuttings from new growth in the spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in a well-draining potting mix and keep them moist until rooted. Rooting typically takes 4-6 weeks. For division, carefully dig up the plant in the spring or fall and divide the root ball into smaller sections. Each section should have healthy roots and foliage. Replant the divisions in well-draining soil and water thoroughly. Ensure the new plants receive adequate sunlight and protection from frost. Lavender can also be propagated from seed, but it is a slower and less reliable method.
